Ionizing radiation sensing has many applications in a variety of industries. Low dose sensing is important for nuclear materials detection and security. Some space applications require measurement of the flux and direction of high energy radiation. Furthermore, it is essential to determine the exact location and amount of radiation directed toward...

Breath alcohol analyzers have been used as a quick and reliable testing device at sobriety checkpoints for individuals suspected of driving under the influence of alcohol. Acetone is typically considered the only endogenous volatile organic compound that can potentially prevent an accurate reading from being produced. It is naturally in a person’s...

Radiation dosimeters are devices used to measure exposure to ionizing radiation such as, X-rays, alpha and beta particles, and gamma rays. The damage that this radiation can cause to a material (e.g., human tissue) is typically cumulative, related to the total ionizing dose received. Therefore, workers who are exposed to ionizing radiation are usually...
